Adult aphid can be with wings and without them, harms more
plants wingless aphid. If melon melon breeds on watermelons,
then the risk of various diseases is increasing dramatically –
curly tops, cucumber mosaic. Ants contribute
infestation of plants by aphids, these are their peculiar “cows”, which
provide ants with sweet discharge.

These little insects survive the winter on the weeds,
growing on the edge of the field. In the spring they crawl into the garden and begin

How to quickly detect aphids

The presence of aphids on plants can be seen unarmed
by eye. It is only necessary to inspect the bushes and watermelon to draw
attention to:

• The presence of white bloom on the bottom of the leaf blade;

• Inflorescences and ovaries wither and crumble;

• Shoots become thin;

it is easy to destroy even by washing them with plain water. If you miss this
moment, then surely all the bushes watermelon on bahche will be populated
pest.

Methods of struggle

Agrotechnical

• In the autumn you need to clean and burn plant residues;

• Dig up the soil at a site at a depth of 20 cm;

• Arrange timely watering and proper feeding;

• Extra root top dressing with solution of potassium chloride in
concentration of 0.5% and superphosphate 0.1 %%;

• Sow seeds early or prepare seedlings;

• Buy seeds of early ripe hybrids, well-resisting
pest:

• Permanently destroy weeds.

Biological

• Plant parsley and dill near watermelon bushes;

• Spread out along the beds with gourds strongly
aphid-repelling herbs – horse sorrel, tomato shoots, dandelion,
celandine and garlic;

• Spray the plants with extracts of tobacco or hot pepper;

• Spray gourds with ash and soap solution (8 l
Water diluted 1 UF. soap and insist there day 1
kg of ash).

Chemical

Watermelons are treated for aphids with insecticides – Fury, Ditox,
Golden Spark, Aketellik, Confidor, Decis. They can be used
only in strict accordance with the instructions. Processing is carried out
only in dry weather, in the evening or in the morning.

If a plantation with watermelons is affected by aphids up to 10% of plants, then
You can destroy the pest with a 60% solution of karbofos. If a
the number of affected plants is greater then you have to use
drug “Commander”. It is one of the most effective and inexpensive.
составов против pest. Most importantly, the effect of the drug
continues after the treatment of plants, and it works even
time of extreme heat.

Important! �”Commander” – a systemic drug is very

if used properly, they will not harm the person.

In greenhouses poorly ventilated, closed space and people
breathing toxic substances is not desirable. No need to use
some insecticides for a long time, insects to them quickly
get used to it, after 2-3 years you don’t
notice.

Folk ways

1. • With a slight spread of aphids on watermelons, you can
use wood ash, adding tobacco dust to it, and pollinate
her affected plant louse. For good adhesion of the drug
is necessary pre-spray the plants with water;

2. • In 1 liter of water soak 200 gr. oven ash, insist 24 hours,
then add 50 grams. finely planed soap,
mix the solution and strain add 9 liters of clean water and
process watermelon bushes, trying to wet the bottom well
leaf blade;

3. • Half a kilo of dandelion leaves, you need to fill a bucket
heated to 40 degrees water, insist this solution for 5 hours,
strain and then spray the plants;

You can dig up the plot.

There is no accurate assessment of the effectiveness of folk recipes.
It can be assumed that there is a small effect of using
